Systems and methods for spectral imaging are disclosed. Such spectral imaging can be used to determine properties of a subject material at different locations upon the surface and/or within the material. For example, strain and/or stress within an imaged area of the material can be determined. A system for spectral imaging can include a light source, a two-dimensional sensor array configured to image light from a two-dimensional area of a subject material, a filter configured to filter light from the subject material before the light is imaged and a processor in communication with the two-dimensional sensor array. The processor can be configured to determine a property of the subject material at a plurality of locations within the two-dimensional area of the subject material. Such spectral imaging systems can facilitate the performance of piezospectroscopic measurements of two-dimensional surfaces in a rapid manner while preserving accuracy.
